Hey --- You need to circle back to figure out what you are trying to do --- and then ask about it. The description you are using here is nowhere near enough to provide useful information to architect a solution.
Here's the deal --- SSO is not something you scrape through --- It is a blocker. Is there an API? Maybe. When you say 'an internal site' --- this does not sound realistic when used to describe the same problem as SSO... an internal site would be 'hey! my company has an undocumented flask/fastapi api which is hosted on an ec2 behind a vpn' --- the advice would be --- figure out who built the api --- request access from your machine. get api documentation which your company has --- because it's internal. don't ask here.
for SSO--- it's like 'this is an ERP - it's on SSO' --- learn the API. Get a service account. You can't get one? Then you probably won't be able to build a solution with Alteryx.
